Copper Properties

List out the Properties & Applications of Copper

Properties:

  • Copper is most widely used metal, because of its high conductivity and low resistivity.
  • Copper is a Nonmagnetic metal and high current density.
  • It is Reddish brown colour with high metallic luster.
  • It has high resistance to corrosion.
  • It is highly malleable and ductile.
  • It can easily soldered and welded at red heat.
  • Its melting point is 10840 C.
  • Electrical resistivity is 1.682 micro ohm cm.
  • Its tensile strength varies from 3 to 4.7 tonnes / cm2.
  • It forms important alloys like brass, bronze….
  • Its boiling point is 25950 C.
  • It has low contact resistance.
  • It oxidizes above 1800 .
  • It has high tensile strength & Toughness.

Applications:

  • Copper is mainly used for wires, cables, Winding of generators and transformers, overhead conductors, bus bars etc.
  • It is used for contacts material for control relays.
  • It is also used for motor starter switches and tap changers.
  • Hard drawn copper conductors is mechanically strong with high tensile strength 40 kg/mm2. It is used for making commutator segments, overhead lines and bus bars.
  • Annealed copper (soft copper) is mechanically weak, tensile strength of 20 kg/mm2. it is easily shaped into any form.
